[cfe-dev] CXCodeCompleteResults and threads

Hey there,

I know that I can call clang_codeCompleteAt from threads as long as I ensure 
no other thread is doing anything with the TU. But can I use the returned 
results from another thread in a read-only manner without caring about locks? 

Or are the CXCompletionString's mapped into the TU for sharing somehow (cmp. 
CXTranslationUnit_CacheCompletionResults) such that I cannot convert safely 
access the clang_getCompletion* functions?

Put differently, is this safe:

- parse TU
- get completion results

in parallel:
- calling clang_getCompletio* on completion results while the corresponding TU 
potentially is reparsed/deleted/... as long as I didn't call 

Thanks, bye
